That happens to follow the abolition of the function of the Devil's
Advocate.
https://en.wikipedia.org/wiki/Devil%27s_advocate
During the canonization process employed by the Roman Catholic
Church, the Promoter of the Faith (Latin: promotor fidei), popularly
known as the Devil's advocate (Latin: advocatus diaboli), was a
canon lawyer appointed by Church authorities to argue against the
canonization of a candidate. It was this person’s job to take a
skeptical view of the candidate's character, to look for holes in
the evidence, to argue that any miracles attributed to the candidate
were fraudulent, and so on. The Devil's advocate opposed God's
advocate (Latin: advocatus Dei; also known as the Promoter of the
Cause), whose task was to make the argument in favor of
canonization. During the investigation of a cause, this task is now
performed by the Promoter of Justice (promotor iustitiae), who is in
charge of examining the accuracy of the inquiry on the saintliness
of the candidate. The Promoter of the Faith remains a figure in the
Congregation of the Causes of Saints and is also known as the
Prelate Theologian.
The office was established in 1587...
Pope John Paul II reduced the power and changed the role of the
office in 1983. This reform changed the canonization process
considerably, helping John Paul II to usher in an unprecedented
number of elevations: nearly 500 individuals were canonized and over
1,300 were beatified during his tenure as Pope as compared to only
98 canonizations by all his 20th-century predecessors.
